Eyes, on the other hand, were anything but simple. First, McGrath swept burgundy shadow across the lids and traced eyes with brown pencil, coloring in the creases and outer corners. Shimmery burgundy shadow completed the high-impact look: She blended it over lids up to the brow bones, past the outer corners, and beneath the lower the lashes. She swiped mascara on top and bottom lashes.

"It's very graphic," says hairstylist Luigi Murenu of the slicked-back hairstyle he created. "The main thing is to make it look like an under-shave, like Rihanna's. Of course, we don't want to actually shave [the sides]—this is much sleeker and more elegant. It's an ode to modernity."

Murenu prepped hair with Kérastase Resistance Volumactive Mousse and blow-dried it straight. He added extensions, cutting the ends in a sharp line. He clipped up the top section of hair from the hairline to the crown to keep it out of the way as he pulled the sides back into a ponytail.
